Valtrex is a widely used medication to treat cold sores secondary to Herpes Labialis and initial episodes of Genital Herpes. Both pediatric and adult patients can use Valtrex as a medication to cure infectious diseases like chicken pox

Valtrex brand is orally administered, once it is inside the body, the remedy will immediately convert into acyclovir and L-valine in your gastrointestinal tract. Valacyclovir is a nucleoside analogue DNA polymerase inhibitor. Studies show that when Valacyclovir is converted into acyclovir, it will have an anti-viral effect against HSV type 1 and 2. Different enzymes will cause acyclovir to undergo conversion; from acyclovir monophosphate to diphosphate and finally to triphosphate. This acyclovir conversion is essential to activate its biochemical properties which will inhibit replication of herpes viral DNA.
